随着Project的开发，可能SVN URL改变了（很多原因，比如域名改变，比如版本升级，再比如一不小心使用了http，想换到https等），那么如果使用SVN，很简单，直接relocate就可以了，但是以前同步使用的Git Project如何跟着变化了，上网查了一下，发现比较有效的来自下面。

General Case
What immediately sprang to mind, and what was suggested e.g. on the mailing list, was to simply edit your .git/config, and change the url= in the section [svn-remote “svn”]. That doesn’t work, however. Instead, I found several suggestions to use variations of this theme:
l Edit the svn-remote url URL in .git/config to point to the new domain name
l Run git svn fetch – This needs to fetch at least one new revision from svn!
l Change svn-remote url back to the original url
l Run git svn rebase -l to do a local rebase (with the changes that came in with the last fetch operation)
l Change svn-remote url back to the new url
l Run git svn rebase should now work again!
This will only work, if the git svn fetch step actually fetches anything! (Took me a while to discover that… I had to put in a dummy revision to our svn repository to make it happen!)

注：红色部分请注意下。
本人已经验证这个方法是可以成功切换SVN URL的。
